Should You Use AI to Write Your Cover Letter?
Using AI for cover letters: where it helps, where it backfires, how to keep your own voice and when to skip the letter completely.
TL;DR: Use AI as an editor and brainstorming partner, not as the author. A generic AI letter reads like every other applicant's and can contain claims you never made. Give it your real facts, rewrite in your voice, check every line, and skip the letter when the application does not ask for one.
The problem with a pure AI letter
Recruiters read many letters in a short time. Text that opens with praise for the company, restates your resume and closes with enthusiasm is easy to spot and easy to skip. It also risks inventing details, such as a project you never did or a value the company never stated.
Where AI genuinely helps
- Structure. Ask for an outline: opening, one story, close.
- Tightening. Paste your draft and ask for a version that is 30 percent shorter, with clearer verbs.
- Tone check. Ask whether any sentence sounds generic, boastful or unclear.
- Questions to answer. Ask it to list what the posting seems to care about so you can pick your best match.
Where it backfires
- Writing the whole thing from the posting alone.
- Adding achievements or numbers you cannot back up.
- Producing the same opening line as thousands of other applicants.
A process that keeps your voice
- Write three bullets yourself: why this role, one result you are proud of, one reason this company.
- Draft a short letter from those bullets, even if it is rough.
- Ask an AI tool to tighten it and flag generic lines.
- Read it aloud. If you would not say it, change it.
- Verify every fact and number.
Do you need a letter at all?
Often no. See Do Cover Letters Matter? When to Write One for when they do and do not matter. If an application makes a cover letter optional and you have no real story to add, a clean resume and well-answered questions are usually enough.
A note on automation
Applyinator does not write cover letters or essays. If a form needs one, it waits for you. That is deliberate, because a letter in your name should be something you wrote or at least read. If you are using a different tool that writes letters for you, review each one before it is sent.
Key takeaway: let AI edit what you wrote, not write what you never did, and skip the letter when it adds nothing.
FAQ
### Can employers tell if a cover letter is AI generated? Sometimes the style gives it away, and some employers say they do not want it. Whether or not a detector flags it, a generic letter does not help you.
### Is it dishonest to use AI on a cover letter? Using it to edit your own writing is common. The honesty issue is claiming things that are not true. Some employers state policies, so check the application.
### What should a cover letter include? Why this role, one concrete result, and why this company, in about 200 to 250 words.
